New-generation antidiabetic medications and dementia risk in older adults with type 2 diabetes: A retrospective cohort study.
Article in The journal of prevention of Alzheimer's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNew-generation antidiabetic medications may have therapeutic potential for dementia, beyond their glycemic effects. However, information from observational studies exploring the association between new-generation antidiabetic use and dementia risk is limited.
objectivesTo examine the association between new-generation antidiabetic medication use and dementia risk.
designRetrospective cohort study using electronic health records of a large non-profit health maintenance organization.
participants84,798 dementia-free individuals aged ≥65y with type 2 diabetes. MEASUREMENTS: Antidiabetic medication exposure was based on purchased prescriptions and was used as a time-varying variable. Exposure periods were defined as periods in which either dipeptidyl peptidase-4 inhibitors (DPP-4i), sodium-glucose cotransporter-2 inhibitors (SGLT-2i), or glucagon-like peptide-1 analogs (GLP-1a) or their combinations were used, otherwise unexposed. Dementia classification was based on the International Classification of Diseases, Ninth Revision codes or antidementia medication prescriptions. Cox regression models were fitted to quantify the association between antidiabetic medication use and incident dementia. Models were adjusted for 13 potential sources of confounding using inverse-probability weighting.
resultsAmong 84,798 individuals with a mean diabetes onset age of 66.4 ± 7.5 years, the median follow-up for dementia risk was 8.7 years (Q1-Q3: 5.4-12.8). Dementia was diagnosed in 11,642 (13.7%) individuals. New-generation medication use was associated with reduced dementia risk (HR = 0.69; 95% CI, 0.66-0.73) and by drug classes (DPP-4i, HR 0.67 [95% CI 0.63-0.71]; SGLT-2i, 0.63 [95% CI 0.56-0.70], GLP-1a, 0.61 [95% CI 0.54-0.69].
conclusionsThe results of this large-scale study suggest that new-generation antidiabetic medication use may be associated with lower dementia risk in older adults with T2D.
